摘　　要：微型涡喷发动机结构紧凑,转子缺乏减振设计的空间。为了解决这一问题,通过对转子进行动力学分析,计算了某微型涡喷发动机的临界转速,并与试车试验数据对比,其2阶临界转速误差仅为3.04%;分析了不同位置、不同不平衡量、不同相位及不同轴承阻尼条件下的前后支承支反力谐响应,得出了装配过程中需重点关注的位置,并给出微型涡喷发动机转子的相关减振设计。The structure of micro turbojet motor is compact and the rotor lacks space for vibration reduction design.To solve this problem,this paper calculates the critical speed of a micro turbojet engine using rotor dynamics analysis.Compared with the test data,the error of the second-order critical speed is only 3.04%.We analyze the harmonic response of the front and rear supporting supports under different positions,different unbalance,different phase and different bearing damping conditions.The key positions in the assembly process are obtained,and the relevant vibration reduction design of the mini turbojet rotor is given.
